I'm gonna say borrow (not from library thought because I can't handle the pressure of due dates and renewals). My borrowing is in the form of swapping through one of the online book swapping sites. I haven't purchased a book in about 2 years since doing this, and I get to have (and hold onto, until I can get around to reading it) almost any book I would have purchased otherwise. Swapping is sort of the best of both worlds, IMO.
